Abstract
The current study was aimed to determine phenolic compounds profile and antioxidant activity of 70% MeOH extract ofTeucrium cavernarum P.H. Davis which is an endemic plant of Turkey.According to LC-MS/MS analysis of the extract, forsythoside A, forsythoside B, luteolin-7-gucoside, cirsimaritin and cirsiliolwere determined as the major compounds. The total phenolic and radical scavenging activities of the extract were alsodetermined. According to antioxidant activity results, IC50 value of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavengingeffect was determined as 0.12 ±0.01 mg/mL. 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radicalscavenging activity was also determined as 1.2 mM trolox equivalent (TEAC).
